Siemens 6ES7134-4GB11-0AB0 Analog Input Module

Siemens 6ES7134-4GB11-0AB0 is a SIMATIC ET 200S analog input module designed for distributed I/O in an ET 200S rack; it provides two current-input channels (2AI) on a compact 15 mm-wide module that plugs into a compatible ET 200S base unit and communicates with SIMATIC controllers via the PLC’s fieldbus interface. Configured as I-4DMU for 4-wire transmitter measurements, the module supports 4-20 mA current signals and uses 13-bit plus sign resolution for the main analog value, with 12-bit resolution allocated for 4-wire transmitter configurations. It features an SF (group fault) LED indicator and a documented cycle time of approximately 65 ms per channel, enabling timely monitoring of fast-changing process signals in automation environments. Powered from the ET 200S base unit’s 24 V DC supply, 6ES7134-4GB11-0AB0 is commonly used to digitize current-loop signals from sensors such as pressure transmitters, temperature sensors, and valve position transducers, supporting distributed I/O for scalable process control and factory automation.
